What is FeNO?

FeNO (Fractional exhaled Nitric Oxide) are very miniscule particles of the gas Nitric Oxide (NO), measured in parts per billion. NO is naturally produced by your body to help combat inflammation and when your airway is inflamed, NO is produced in the lungs and exhaled on the breath.

The production of nitric oxide is often found to be higher in inflammatory conditions such as asthma and therefore FeNO monitoring can be used for the detection and management of such conditions2, but also to differentiate between COPD, ACOS other and interstitial lung diseases that are not assessed by other means, such as lung function3.

Airway inflammation is a central process in asthma and other lung diseases1. Being able to detect eosinophilic airway inflammation and monitor a patient’s response to treatment is regarded as a gold standard in the management of respiratory diseases.

Nitric oxide measurement is not intended as a stand-alone method for diagnosis and should be used in conjunction with other evaluation methods and tests4.
Using FeNO measurements to evaluate airway inflammation in asthma represents a significant advance in respiratory medicine5, but until now this has been an expensive test to deliver in everyday practice.

Benefits
● Non-invasive, quick and easy to perform5
● Shows patient’s response to treatment, enabling the correct prescription of medication and safer/monitored adjustments
● Shows patient compliance
● Aids in identifying patients who do/do not require on-going treatment6
● Shown to be superior to the majority of conventional tests of lung function, such as peak flow recording and spirometry5
● Aids in differentiating between allergic (eosinophillic) and non-allergic asthma7.

NObreath – what is it?

The NObreath is a FeNO monitor which can be used to measure airway inflammation for the management and diagnosis of asthma. Recommended by NICE and conformed to ATS & ERS guidelines, the NObreath makes FeNO monitoring quick, and easy plus it is completely non-invasive, with the ability to monitor airway inflammation in both adult and child patients. Furthermore, the ambient monitoring mode enables you to check ambient levels of NO.

FeNOchart™

FeNOchart™ is a FREE patient management software for the NObreath FeNO monitor.
Patients can be synchronised between the NObreath and computer, enabling you to safely back-up and store patient profiles and results. The software also has the ability to capture readings directly from tests when the NObreath is plugged into the computer, plus graphs can be plotted and reports generated to share with patients and monitor FeNO levels.

Worldwide Forum

With the purchase of a NObreath you are eligible to become a member of the NObreath® forum – a place where you can seek answers, offer help or simply discuss FeNO techniques, findings and much more with other healthcare professionals from around the world.
